Abstract

Disclosed herein are novel amorphous tetrafluoroethylene/hexafluoropropylene (TFE/HFP) copolymers, which are more random than previous amorphous TFE/HFP copolymers, as well as a novel high productivity continuous process for making these polymers. The polymers are particularly useful in the form of coatings, films and encapsulants.
